Quote from Blizzard »
Eternal Conflict is sort of an "expansion" - an event lasting for several months, with new heroes and battlegrounds!
First Blizzard world entering the nexus.
Leoric - very unique warrior
Trait: when he dies, becomes a Wraith and continuously "haunt" and bother enemies even while dead. After the respawn timer is over, he respawns where the Wraith is, rather than at the base.
Heroic 1: Tombstone - creates a U-shaped wall at target location, effectively trapping enemies in that area.
Heroic 2: March of the Black King - after a small wind-up, slashes forward dealing high area of effect damage and being unstoppable.
Monk - very nimble support (still early in development), jumps from one place to the other and can heal allies.
Very unique in the sense that his Level 1 Talent choice is actually a Trait Choice!
He can choose from more offensive of defensive "stances" as his Trait - which suggests Mantras could be these Traits.
Appears to have Seven Sided Strike as one of his skills.
Treasure Goblin - spawns right before the gates open, and if heroes manage to kill him before he escapes they get bonus gold at the end of the match!

Quote from PC Gamer and PCGamesN »
Treasure Goblins have a chance to spawn in any battleground.
Two Goblins spawn per map, one per side, before the Gates open.
Treasure Goblins award 100 gold and a special portrait when killed.
That is a sort of side daily quest - but they do not replace your normal daily quests. They stack!

Hero Level 9 -- A new 750 Gold reward has been added. This Gold reward will also be retroactively granted to players for each Hero that reached level 9 prior to today’s patch.

To moze niech ten bonus juz zostanie na stale? Nastepnym razem dadza + milion

Od 2 do 6 lipca bonus 100% do zdobywanego doświadczenia.

...Have you ever wondered why map-hacking historically has been such a big problem in StarCraft? It's because every player has complete game state in memory, including units hidden by fog of war. For example, League of Legends does not have this problem, because your client has no information about hidden entities until they actually become visible to your team. But League does not have to transfer updates for hundreds of units. And StarCraft does not have a choice.
Dota 2 uses Source, primarily an FPS engine, developed all the way from Quake. It is client-server, and sends game state snapshots once every 50 ms or so. The client interpolates between those snapshots to create smooth experience.
Another drawback that deterministic lockstep simulation imposes is having everyone synchronized. That means waiting for users who lag for one reason or another (network- or even performance-related). If you ever watched StarCraft II tournaments, you've probably seen that spectators can lag games. It is because there's no central authority who dictates the simulation. Everyone, even spectators, have to coordinate, have to have exactly the same game state in order to incrementally advance simulation forward. This means waiting for the slowest party...
